In plain words

What the trial is, and whether it could suit you

Phase 1/2, dose escalation and expansion study designed to evaluate the safety and tolerability of zidesamtinib (NVL-520), determine the recommended phase 2 dose (RP2D), and evaluate the antitumor activity in patients with advanced ROS1-positive (ROS1+) NSCLC and other advanced ROS1-positive solid tumors. Phase 1 will determine the RP2D and, if applicable, the maximum tolerated dose (MTD) of zidesamtinib in patients with advanced ROS1-positive solid tumors. Phase 2 will determine the objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR) of zidesamtinib at the RP2D. Secondary objectives will include the duration of response (DOR), time to response (TTR), progression-free survival (PFS), overall survival (OS), and clinical benefit rate (CBR) of zidesamtinib in patients with advanced ROS1-positive NSCLC and other solid tumors.
